For those that still dont get it!
The sensors normal operating parameter are to be within .9-1.1 bar atm.
As you can see the sensor output shifts can easy hit 10% or more pre- turbine.

Now factor in a 1.75 to 2:1 exhaust manifold to intake pressure ratio at 20psi of boost...

Well, the amount of boost is irrelavant persay it just the exhaust pressure.
But, the normal design criteria for a system to have good response is 1.75 to 2:1. So at 10psi it would be at 20psi. But, in all fairness, the STS seem to be pretty low based one some of the response stuff I have seen, but enough to skew it 1 full AFR
